Chinas new radar has greatly increased its surveillance range by inducing wild guesses from outside media.

China is not the only country to develop this technology, the article said. Raytheon Corporation of the United States won a patent for similar systems in 2016. Raytheons design includes a signal launcher and several receiving vessels.

The statement originated from the reports of Hong Kong media.

A Hong Kong South China Morning Post article entitled China Navys newcompactradar will enable it to monitor areas of Indian size said that land-based OTHR radar was originally developed by the US and the Soviet Union during the Cold War. The radar monitors areas within thousands of kilometers by transmitting radio waves to the ionosphere and reflecting them back into the Earths atmosphere. However, due to some shortcomings of the radar, many similar facilities have been closed or suspended.

What is over-the-horizon radar

Experts believe that the over-the-horizon radar understood in the harbor media articles should belong to the sky-wave over-the-horizon radar, which covers a large area and is difficult to be used in shipborne. Experts are reluctant to comment on the type of OTHR radar that won the award. However, he said that, based on the current public information, reports from foreign media are likely to be speculative.
